Champagne was Dom; Iced vodka and caviar from the USSR. First Class often not that full. For a long time, they would not put non-revs in F (But business class was fine too) and it was also very difficult to upgrade even if Royal Medallion (FO). In fact, I think that initially no amount of miles in the world could get you a free F ticket.
This discussion make me long for the good old days, which will probably never return. International or Domestic, it's incredible how far the quality of service has fallen. I guess the good news is that, with the exception of the total phase out of domestic F, it really can't get much worse.
